SÖDERHAMN Sectional, 5-seat, Viarp beige/brown — Assembly Overview

Sofa assembly is a category all its own — heavy components, awkward dimensions, and mechanisms that need to function reliably for years. The SÖDERHAMN Sectional, 5-seat, Viarp beige/brown averages 1 hour and 40 minutes based on 2 real builds, with a moderate difficulty rating. Two people are essentially required for any large sofa build — the sections are too heavy to maneuver safely solo. Clear plenty of floor space and protect it before you start.

Why this build takes as long as it does

Sofa assembly is physically demanding more than technically complex — the sections are heavy and unwieldy. The mechanism arms (if this is a sofa bed or recliner) are the most critical step and need to be tested before the armrests go on, because they can't be adjusted easily afterward. Two people are essentially required for any large sofa build.

⏱ Time Breakdown

Estimated split based on how real builds typically run

What usually slows people down

• !The weight — sofa sections are much heavier than they look and hard to maneuver without damaging the floor
• !Connecting modular sections tightly enough — visible gaps appear if the connecting hardware isn't fully tightened
• !Mechanism installation on sofa beds — the pull-out arm has to be tested before armrests go on
• !Assembling in the wrong room and then trying to move it through doorways

🛠 How to Assemble It Faster

1. 1Assemble in the room it will live in. Moving a large sofa through doorways after assembly is the most common avoidable mistake.
2. 2Put moving blankets under sections before flipping — sofa leg feet scratch wood and tile permanently.
3. 3Test any pull-out or recliner mechanism fully before attaching armrests. The mechanism is inaccessible after armrests go on.
4. 4Tighten section connectors firmly before sitting on the sofa — loose connectors cause visible gaps that widen with use.

Step-by-Step Assembly Guide

1. 1Clear a large area — sofa sections need room to maneuver. Protect floors with moving blankets.
2. 2Assemble any modular sections separately before joining them.
3. 3Attach legs or feet to each section while they're upside down on a padded surface.
4. 4Flip sections right-side up and position them. Join sections with the connecting hardware.
5. 5Install any mechanism arms for sofa beds or recliners. Test the mechanism before finalizing.
6. 6Attach armrests. These are usually the last structural step and define the final shape.
7. 7Add cushions and test the full sofa. Check that any pull-out mechanism operates smoothly.

Common mistakes to avoid

• ✕Assembling in the wrong room — large sofas are nearly impossible to move intact through interior doorways
• ✕Not testing the pull-out mechanism before attaching armrests
• ✕Leaving connecting hardware between sections slightly loose — causes persistent gaps
• ✕Forgetting to protect the floor before flipping heavy sections

Easier alternatives to consider

If you want less assembly time or complexity

If you prefer IKEA's design and price point, the original is still a solid choice — just budget the extra setup time.

What affects assembly time

Is this worth assembling yourself?

Sofa assembly is about physical effort more than technical complexity. If you can get a second person, you can almost certainly handle it. The main reason to consider professional help is if you're moving the sofa through a difficult floor plan — assemblers know how to handle doors and staircases with large sections.
